[PATCH 05/14] platform/x86: dell-wmi: remove sparse_keymap_free() calls

From: MichaÅ KÄpieÅ
Date: Thu Mar 09 2017 - 07:12:35 EST


As sparse_keymap_setup() now uses a managed memory allocation for the
keymap copy it creates, the latter is freed automatically. Remove all
calls to sparse_keymap_free().

As this reduces dell_wmi_input_destroy() to one line, replace all calls
to that function with direct calls to input_unregister_device().
